To all whom it may concern:

Be it known that I, HARRY F. ANDERSON, citizen of the United States, residing at Kan.- sas City, in the county of Jackson and State of Missouri, have invented certain new and useful Improvementsin Printing-Presses, of which the following is a specification.

I My invention relates 'to' improvements in printing presses.

My invention is particularly adapted for use in connection with D roller plate printing presses. As commonly used these presses are hand driven, that is the shaft which forces thereciprocativev bed forward is rotated by hand, for the reason that so far as I am aware no means have been provided by which presses of this character may be power driven and produce results as satisfactory as hand driven presses.

The object of my invention is to provide driving mechanism by which the reciproca tive bed of a D roller plate press may be started without perceptible jar, thus eliminating the princlpal objection to the use of power for driving presses of this type.

My invention provides further a novel clutch mechanism hereinafter described and claimed. I

Other novel features are hereinafter fully described and claimed.

I11 the accompanying drawings, illustrative of my invention, Figure 1 is an end elevation view of a D roller plate printing press provided -with my invention. Fig. 2 is a front elevation view of what is shown in Fig. 1. Fig. 3 is-across section taken on the dotted, line ab of Fig.2. Fig.4 is a central vertical sectional view of the clutch mechanism and parts connected-thereto. Fig. 5 is a horizontal sectional view taken on the dotted line c-d'of Fig. 4. V Fig. 6' is across section taken on the dotted line cf of Fig. 4. Fig. 7 is a cross section taken on the dotted line gh of Fig. 4. Fig. 8 is a cross section taken on the dottedline i+j of Fig. 2. Fig. 9' is a sectional view taken onythe curved dotted line 7cl of Fig. 7 showing the shape of one of the notches in the driving pulley. Fig. 10 is a vertical sectional view taken on the dotted line of Fig. Fig. 11 is a top view of one end of the D roller and some of the parts connected therewith, also a portion-of-the bed. and abutment carried thereon. Fig. 12 is a vertical sectional view of the abutment carried by the bed. Fig. 13 is a perspective view of the bolt carried by the sleeve. Fig.

14 is avertical-sectional view taken on the dottedline 0p"of- Fig. 2, showing the D roller in contact witha card mounted on the engraved'plate carried on the bed. Fig. 15 is a horizontal sectional view taken on the dotted line gr of Fig. 1;

Similar. characters of reference denote similar parts;. ",1 denotes the. two vertical ends of the frameof an ordinary D roller plate press.

' 2 is the horizontal rotary roller shaft rotativelymounted in bearings 3 mounted one in Intermediate the ends *1 'a D=roller 4 is secured to the shaft 2. Below the D roller 4 is the horizontal bed 5 reciprocative under the roller 4 and supported by rollers 6 of which there are four rotatively mounted two upon each of two horizontal tie rods 7 connecting the ends 1, said rollers 6 being mounted two in each of two longitudinal grooves Son the under side of the bed 5. On the shaft 2 at one end of the D roller 4 is secured a cam 9 adapted, when the shaft 2 is rotated to strike an abutment carried by the bed 5 for forcing the bed forward a part of its forward stroke, the bed being carried the remainder ofits forward stroke by the pressure of-roller 4 upon the card 10 resting upon the engraved plate 11 carried upon the upper side of the bed 5. It is of course understood that the card 10 after each printing operation is replaced by a fresh card.

The abutment comprises preferably a member 12 the lower end of which is provided with a transverse holein which is mounted a bolt 13 adjustable lengthwise of a slot 15. The upper end of the member 12 is bifurcated and 1 has rotatively mounted between the arms a wheel 16 the periphery of which is encircled by a resilient tire 17, of rubber or leather. The cam 9 strikes the tire 17 thus starting the bed forward without jar.

Upon one end of the shaft 2 is mounted a sleeve 18 preferably circumferentially adjustable on the shaft 2 to enable the adjustment of the sleeve relative to the D roller 4, and rigidly secured to the shaft by any suitable means, such as a set screw 19. On the sleeve 18. is rigidly secured a collar 20. The outer end of the sleeve has a peripheral flange 21' between which and the collar 20 is rotatively mounted a driving pulley 22.; The inner end of the pulley 22 is provided with one or'more notches 23, each of whichinclines inwardly relative to the adjacent end of the pulley and then curves outwardly to an abrupt end which serves as a seat for a bolt 24 longitudinally movable in a longitudinal groove 25 in the periphery of the sleeve 18. The bolt 24 is moved in the groove 25 against the bottom of each notch 23 by coil spring 26 one end of which is mounted 1 a hole in the sleeve and the other end 0 which is mounted in a hole in the inner end 0'" the bolt 24.

adjacent end 1 of the frame When the bar 28 1S raised as shown in Fig. 6 it will remain in the notch 27 and prevent the bolt being iorced into the notches 23 when the driving pulley is rotated on the sleeve 18. To depress the bar 28 to release the bolt 24:, it has pivoted to it the upper end of a V61 tical connecting rod 29, which extends through a vertical hole in a bracket 30 secured to the adjacent end 1. The lower end of rod 29 is pivoted to a pedal 31 which is pivoted to support 32 secured to the floor. A coil spring 3?; encircling the rod 2 has one end bearing upon the bracket 30 and the other end upon the bifurcated upper end of said rod. The tension of the spring 33 normally forces the bar 28 toward the position shown in Fig. 5. The starting end of each notch 23, that is the end which first passes before the end of bolt 24, is the inclined end.

Alter a card 10 has been pr i L ll tioned on the engraved plate 1 is depressed thus withdraw' ig notch 27 and permitting the sp; force the bolt 24 against the cent end 0 the driving pulley 22. As soon as a notch 23 passes before the bolt 24, the bolt will lOllOVf the inclined bottom and will then be l'orced along the curved bottom outward a; 1i st the pressure of the spring 26, thus causing the bolt by its pressure on the curved bottom to slightly start the sleeve 22 beiore .the bolt comes against the abrupt end the notch 23, and thus taking oii the jar ol start At the same time the earn 9 will st ":0 resilient abutment or tire 17 and wi start the bed 5 forward without jar.

time the parts will have moved to trio position shown in dotted lines in Fig. 10, the rollerel, or D roll r, will bear upon the card 10 and by its pressure thereon and upon the plate 11 will continue the forward movement of the bed 5 until the D roller has rotated so as to clear the card 10. The bed 5 will then be retracted to its original position by any suitable means. in the drawings 1 have shown a rope 34 having one end attached to one end ol the bed, the rope then passing over a pulley, shown in dotted lines in l, the lower end of the rope being secured to a weight 35. To the rope may be attached the upper end of a spring 36, the lower end of which coil spring is attached to the floor.

lily the The under side of the bolt 24 is provided with a transverse notch 27 adapted 3 to receive the beveled end of a liOilZODlill bar 28, the other end of which is p voted to the i i The coil s 'ing so may be dispensed with. i but i have lound that it qniclrens the starti ing of the bed 5 on its return nn'iveinent. it i will be undu'stood t the rope 2b: is nii tached to toe end ol' the bed adjacent the the rope in; passing over the pulction such that theircight 335 member i lev 3.
